Study Notes
Oxygenation and Respiratory System
- Primary function of diffusion in the context of oxygenation: to facilitate the exchange of oxygen and carbon dioxide between the air we breathe and the blood.
Pulmonary Circulation
- Main function of pulmonary circulation in the respiratory system: to transport deoxygenated blood from the heart to the lungs, and then return oxygen-rich blood from the lungs to the heart.
Hypoxemia
- Definition of hypoxemia: a state of insufficient oxygen in the blood, characterized by low oxygen levels in the arterial blood.
Ventilation Regulation
- Regulation of ventilation in the lungs: controlled by the respiratory center in the brain, which responds to changes in blood carbon dioxide levels and pH.
Alveolar Gas Exchange
- Role of alveolar gas exchange in the respiratory process: to facilitate the exchange of oxygen and carbon dioxide between the air we breathe and the blood, allowing oxygen to enter the bloodstream and carbon dioxide to be removed.
